ARTHUR KOPPEL, OF BERLIN, GERMANY.

RAIL-FASTENING.

SPECIFICATION forming part of Letters Patent No. 749,936, dated January19, 1904.

' Application filed October 2, 1903.

To all whom it may concern.-

Be it known that I, ARTHUR KOPPEL, residing at Berlin, Germany, haveinvented certain new and useful Improvements in and Connected withRail-Fastenings, of which the following is a full, clear, and exactspecification.

My invention relates to method of and means for connecting rails tosleepers, and is more especially applicable to field-railways, theobject being to provide an improved fastening which will obviate the useof separate chairs, bolts, pins, or other like small fittings, thefastenings being so effected that a reliable security against shiftingand turning is attained.

According to' the invention a cramp-like bending of part of a metalsleeper is utilized to hold the rail on the one side, preferably theinner side, the foot of the rail fitting under the overlapping or bentpart of the cramp. On the other side of the rail, opposite to the cramp,a tongue is bent up from the flat part of the sleeper, or the tongue maybe formed from the end of the sleeper. This tongue is then bent backover the foot of the rail and pressed, together with the inclosing partof said foot, so as to dip somewhat below the level of the top of thesleeper, forming a common depression or indentation both in rail andsleeper, and thereby effecting an intimate connection of the rail withthe sleeper for the purpose of securing them against shifting andturning.

The invention is represented in the accompanying drawings, wherein- 1Figures 1 to 5 are sections and plans of the new rail-fasteningaccording to one modification of the invention.

Fig. 1 shows in elevation and section the cramp a, which is previouslyformed in the sleeper and which overlaps the foot of the- The left-handview shows by dotted lines a tongue I), also previously formed in amanner admitting of insertion of the rail, such tongue after the railhas been placed in position being bent down onto the foot of the rail,

.(J D, Fig. 1, and Figs. 3 and 5 side views showing the cramp a andtongue 6, respectively. The bending or indenting is effected in anysuitable manner, but preferably by a lever jack or tool. When the leveris applied to the rail, the pressing-plate first forces the tongue 6into position over the foot of the rail. The tongue is then firmlypressed through or indented in the middle, together with the foot of therail and the'part of the sleeper underneath. The same manner of securingis efiected-if the end of the flat sleeper be used as a tongue and bentover and pressed through, as before described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is v 1. In combination with a rail andsleeper, a cramp formed on the sleeper engaging with the rail on oneside, and a tongue bent up from the sleeper engaging the rail on theother side substantially as described.

. 2. In combination with a rail and sleeper, a cramp formed on thesleeper engaging the rail on one side and a tongue bent up from thesleeper engaging the rail on the other side, said tongue and thatportion of the rail engaged thereby being bent down'into the sleepersubstantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

ARTHUR KOPPEL.
